'lhisinvention relates to boxes made of cardboard or other flexible material, and has special reference to means for utilizing inte-` gral portions of the box Vwalls as means for.

attaching the box walls to the bottom of the box, and also for providing Vanv ornamental feature in connection with the margin of the box bottom so as to eliminate the necessity or desirability of usingother or separate'fea- 1o tures to provide this ornamentation.` f

An object of the invention is toprovidean im roved box wherein a strip of cardboard orv ike materiahforming the box sidevhas a continuous defined part designed and construeted to be placed in a definite position Y against a bottom or top wall in order. that such strip may be attached atthe bottom or top AWall in a definite, predetermined relationship in which said strip extends from the bot-n tom or top walls of the box at definite` andv predetermined distances from the edges of said walls and in a relationship in which thev edges of the defined portions of saidstrip are Hush with the edges'of said walls and coopf erate therewith to form a thickened area or base outside'the box and projecting laterally from `said stri Another ob]ect of the inventionis to vide an improved box of the type mentioned 30 wherein said strip and/or said defined portion thereof are provided withindicia for guiding the placement of the strip inproperV positionon the bottom or top wall of the vbox for attachmentthereto.

'Other objects and advantages of the presf ent invention will clearly appear from the following descriptiom'reference being made to the accompanying drawings, in which Fig. 'l is a plan view of the rectangular 40 strip from which formed.V

v Fig. 2 is a view looking toward one edge of said strip and showing indicia which are formed to permit the strip'to be bent properly and which guide the proper positioning of the strip for attachment to the bottom or top wall of the box.

'Fig'. '6 is anend viewv ofthe strip which. v forms the side wall of the box.

`In the embodiment of the invention ,shown` f in the annexed drawingse the bottomlwall 4of the box comprises a sheet l of'cardboard or; other kappropriate material.` This bottom wall maybe lmade in` any; desired :contour or form, and I do not restrict myself to the one. form shown. l For the purpose of illustrating one exemplification of. thelinvention I have shown the walll as provided withtwo'lobes 2 and in one-edge between theflobes A2 av notch formedY withV asharp corner 3 v rdirectly i or. nearly in alignment 'with the sharp `point 4. at the oppositeedgeof the sheet l.r Theentire edge of the sheet l is cutwith assharpgdiefso as toprovide an ornamental edgewhichfis ex-l posed when the box is completedlandwhi'ch-I define asV a cut edge'. Accordingly, a p,re ferred embodiment of the Tinvention yconsistsbf a boxin which they bottom wallof the,

box and the top wa-ll of thelidlare of any dee;

sired shape and.` haveexposed cutfedges,y .i-

which are defined herein as bottomand top walls havingcut edges. i

. Y In describing vthe invention, I `specifically describe the box vstructure with the explanaf.

tion that the lid structure is the same, thezlidv being shown in Figs. 4 and 5 of the drawings@ The same reference numerals vthat are ap# plied tothe. b ox properare applied to like parts of the lid with the exponent a.. i

The box `side wall Vis preferably formed i with a single elongated strip, 5 having a de`v fined portion 6 integral with one edge thereof. The edge of the definedportion 6 is cut by: a sharp die so as to provide Lan ornamental cut edge to be laid. fiush with .the ornamental cut edge ,of the `bottomwall l of the box.` A` 'n V-shaped notch 7 iscut in andthrou'gh the `defined portion `6 and has adepth exactlyv equal to thevwidth of said dened portiony 6. i

That is to say the apex of the V-shaped notchl `7 is atthe line 8 which is parallel with the cut-A 3 to the sharp point 4. c The opposite'endof edge of the defined portion 6. The line 8 deof the definedportion6, if such facility is needed because ofthe character of the matevrial used. In tlie assembly of the box ele-t ment, the wall strip 5 is bent transversely and sharply along the line 9, this bend extending from the apex of the notch 7 to the opposite edge of-saidstrip. r The line 9 constitutes an indi'ciuin cooperating with the notch 7 to vguide the positioning of the strip upon the bottom wall and to prevent said strip from being placed in a position in which the defined portion 6 .crosses the plane of the sharp corner 3 vopposite which theline. 9 must be placed. The sharp corner formed by bending the strip 5 sharply alongftlie line 9k is.

placed directly on tlieline from the corner 3 to the point 4.

The defined portion 6 hasan extension V10 projecting beyond one end of the strip 5', said extension havingan inclined edge 11 intersecting theend 12 ofthe strip at the line 8. The edge 11 is arranged at such an inclination thatwhen the wall strip 5 is assembled on the bottom wall ofthe box said' edge 11 is` upon the line runningfrom the sharp corner the defined portion 6 is formed with an extens1on 1'3similar to vthe extension 10,. and'rhavingV an edge Mthat abuts againstV the edge 11 when the side, wall ofthe box is assembled upon the. bottom walh lThe end of the strip .5 oppositefrom end 11 isprovi-dedwith an elongation. 15 deiinedfrom the wall formingrportion ofthe strip 5 by a line 16 which may'Y be visibleA or not`A as desired, and which extends from thev line to the opposite edge` of said strip 5. The line .1 6'mayfbe a crease or a score line so asl to facilitate the bending ofthe elongation 15 to provide aninnerlap for the opposite' endof the strip and for attachment thereto by glue,y or other appropriate fastening means. Thus, as clearlyshown in Fig. 3 of the drawings, the elongation 15 is bent sharply-along the line 16 so vasvto lieY against the inner side of the opposite end of the wallstrip 5, to which said Y elongation is attached by glue or otherwise as desired.

Any or all ofthe lines Y89, and 16, may be score lines orfcreases if the character of material used makes such score lines or creases desirable, so as to function as indicia for the proper bendingy of the strip and so as to permit use` of the defined portion V6 to attach the side walll to thebottom, wall of the box and in the` proper relationship thereto, and to permit bending of the elongation 15 for use in attaching together the ends of the wallstrips.

In the manufacture of my improved box the bottom wall is cut in the desired shape and, if desired, the Vout edge thereof may be left exposed. The bottom wall 1 may be cut in hea-rt shape, or in any other shape, to utilize the principles of the invention. The strip 5 is cut of the desired length and in the shape toiprovide the" defined portion 6 having a width exactly equal to theV distance atv which the side wall of the box is to be placed iii wardly from the edge of the bottoni wall and so as to seat upon themarginal portion of the f;

bottoni wall and have its edge fiushwith the edge .of said bottom wall. The notch 7 constitutes a guide indicating the bending line of theY strip l5v which may alsobe provided with a visible crease or score line 9 to facili- Y; tate the bending and to cooperate with the notch to .prevent bending at the wrong place.

The definedl portion 6 ofthe strip 5, is bent;

laterally and the strip 5 is bent to the proper shape to form the side wall vof the box. During attachinentofthe strip 5' to the bottom wall continuou'spressure is applied upon the defined portion 6to Vpress the saine upon the marginal portion ofthe bottom wall ofthe box.

This pressure holds the definedporf tion 6 from tearing or, breaking which'v might' otherwise occur, and also operates to lcause theV glue 17 to hold y the defined portion. 6A upon andin firm connection with the marginal por'- tion of the bottom'wallv 1.v In this assembly ,1.1

the wall'strip 5 isbent along the line 9 and said bend is placed on the'line running from the sharp corner B'to the sharp point 4. The edges 1 1 and ,145 abut togethclras do theedges of` the notch 7 The pressure upon the defined port-ion 4fiduring lthe assembling and attachment of the side wall to the bottom wall of the .boxis considerable and continuous, and is timed/so as to apply the pressure at the propertime t0 preventlthe .edge of the defined portionfroni tearing orbreaking or otherwise becoming nialformed 'at any point. This assembly of the side wall of the box upon the bottom wall may be obtained in a boxn making machine, adapted for this purl pose. c. v

4 y box oft-his character may be manufactured at; comparatively low cost and produced in an ornamental form with 'cut exposed edgesv of the base 'and of the attaching defined portion 6 of the side wall so as to eliminate the need ornecessity of using. separate attaching strips for the purpose of obtaining this attachment, ovr for the purpose of ornamentation. By making the box of coated cardboard a box of highly ornamental appearancepmay be thus constructedrat in uch lower cost than by other practices with which Iam familiar. i
